I purchased these about two years ago. The soles still have plenty of life left, as I didn't wear them often. There's no impact on the comfort. These are originally priced at 16,280 yen. Here's an excerpt from the product description on the website: JASPER is The Original Outdoor Sneaker. A long-selling original outdoor sneaker. This outdoor sneaker is a hybrid of climbing shoes and comfort shoes. It's a Hero Product that combines brand, design, style, and value price.
